Thanks Sandra that's reassuring to hear. I did tell her that her dosage was quite low. When your level and only tested every three months you don't know it's dropping but at the moment she is being checked every two weeks.

I'd never heard of the machine but will definatley look into it.

I'm also in a panic as have to up my bisoprolol from 1.25mg to 2.5mg.

Might wait a bit though as have an awful ear infection at the moment to top things off.
